-My presentinvention relates generally to cotton pickers of the rotaryspindle type, and

more particularly to thedoiiing or removal of cotton from. the spindlesafter it has been picked. More especially my present invention hasto dowith the removal of cotton from the spindles of that character ofspindle machine wherein the spindles; in addition to, their for eachvertical row of spindles, each stripper bar receiving the severalspindles of its and constantly controlled by endless camrow in freelyrotatable relation therethrough guides, so that during the revolution ofthe spindles around a verticalfaxis, the several stripper bars will beshifted lengthwise of the spindles between extreme inner and outerpositions-,pThujs the bars will be at their inner positions at thepicking station so that practically theiull lengths of the spindleswillbe effective in the picking operation, and will 7 be at their outerpositions at'the dofiing sta- 'tlO'HSOj that theipicked cotton Will'bepushed removed; I

above described; l 7 i I My invention, has for its further objects, theprovision of a simple, efiectiveand durable arrangement which will beeconomicaland of, great strength, and my invention has .still furtherobjects relating to details of con- StructiomcombinatiOn and operationwhich I may be more thoroughly understood and better appreciated fromthe following descripe tion,,referring to the accompanying draw- 1ngs.q, p

Inthe drawings,-which form a part ofthis' specification,

Figure .1, .is a vertical, sectionalview through a picking apparatus,illustrating the practical application ofsmy invention.-

Figure 2 is a top pl 11 view thereohpartly in section. 1 l v i Figure 3is avertical sect-ionalview-taheni through the upper portion of one ofthe spindle, carriers and a portion of one of the stripper bars and itsadjacent guide, and,

, Figure 4 is a detail perspective view of'one I of the stripper bars. or V Referring now to these figures,"and particularly to Figures 1 and2,- I have shown the spindles 10 supported in vertical rows,- as inPatent 1,387,176 above referred to, upon cylindrical vertical carriers11 "which latter: have crankarms 12 at their upper ends provided withrollers 13 engaging a stationary upper cam track 14% This arrangementserves to turn the carrierson, their, axes asthey revolve in a seriesaround a vertical carrier' wheel shaft 15,"t h e carriers 11 havinghearings at their upper and lowerportions inthe carrier wheel, of which,the necessary ,portions so 'far as present illustration is eoncerned,may be seen at the shaft 15'.v

'lhus as the shaft 15, isrevolvjed; theseries;

a stripping mechanism of the character first I of carriers 11 move withit and as the car riers revolve they are controlled by the cranks I 7l2- and cam 14 so thatthey outstand in paral-; Such 'a machine 1s,,, fornstance,j

lel relation at the picking station as shown at V During this operationat the doffingstation the ends of the spindles pass closely adjacent toa rotating doffer 18 adapted to remove cotton from the spindle ends, andit is to be understood that, at the picking station, the severalspindles are rapidly rotated upon their own axes by virtue ofsuitablemeans, for instance their gears 19 engaging racks 20.

According to my invention, a stripperbar 21 is provided for eachvertical series of spindles 10, or, in other words, for each carrier 11.Each stripper bar has a series of openings 22 through which the severalspindles project. Each bar 21 is moreover securely fastened at 23 at itsends to hearing brackets 24 having apertures 25 arranged to receivetubular guides 26 which outstand from the upper and lower ends of eachcarrier 11. The brackets 24 are sufficiently thick so as to insure freesliding movement of each stripper bar with respect to its upper andlower guides 26, and each bracket also has a vertically projecting camengaging extension 27 for a purpose which will presently appear.

Each tubular guide 26 is longitudinally slotted as at 28 and houses acoil spring 29 whose outer end abuts a rounded end cap 30 closing theouter end of the guide. The inner end of the spring engages a cross pin29 oustanding at its ends through the slots 28 and bearing against theadjacent stripper bar bracket 24. H

Thus the springs 29 within the tubular guides 26 serve to maintain thestripper bars 21 adjacent to the inner ends of the spindles 10 except atsuch times as these strip er bars are moved outwardly along the spindles by a cam operation as the carriers successively approach the doflingstation.

Referring partlcularly toFigure 2, it will be seen that I provide a cam31, it being understood there will be'two such cams, one above, and onebelow, the series of spindles,

located adjacent to the dofling member 18.

One end of this cam is sufiiciently close to the moving series ofcarriers 11 to engage the bracket extensions 27 of the several bearingbrackets 24, while the other end of the cam is so disposed as to releasethe bearing brackets immediately after the successive vertical series ofspindles pass the dofier 18.

Thus by the use ofstripper bars I am onabled to more effectively stripcotton from the spindles than can be accomplished inv other ways,,and byspring controlling the. stripper bars and returning the same to theirnormal positions adjacent to the innerends of the spindles immediatelyafter the cotton has been removed by the dofl'er from the outer ends ofthe spindles, I am able to avoid any interference with the remainder ofthe moving'parts necessary with this type of cotton picker.

It is obvious, of course, that the cam 31 may be supported in a rigidmanner either in connection with the supports of the dofler or eachseries of'spindles, a strip portion of the revolution of the supports,and

means for returning each bar to the inner ends of its series of spindlesupon release from said cam.

2. In a cotton picker, a series of bodily movable spindle supportsrotatable upon their mvnvertical axes, a series of spindles carried byeach support, a stripper bar shiftable on each series of spindles, cammeans for moving said stripper bars in one direction, and spring meansfor shifting the stripper bars in the opposite direction;

3. In a cotton picker, a series of bodily movable spindle supports eachrotatable on its own vertical axis, a vertical series of spindlescarried by each sup ort, a stripper bar shiftable on each series 0spindles, guide spindles, a rotatable and bodily movable supporttherefor having outstanding guides, a

stri per bar movable on said spindles and having portions slidablyengaging said guides, and s ring means in connection with said guides orurging the stripper bar toward the support.

6. In a cotton picker, :1. vertical series of spindles, a rotatableandbodily movable support therefor having outstanding slotted guides, astripper bar movable on said.

spindles and having ortions slidably engaging said guides, an springshoused withm said guides and having means engaging the stripper bar forurging the latter inwardly toward the support- 7. In a cotton pickerhaving rotatable spindles arranged in vertical series, and a bodilymovable and rotatable support for r bar for each support shiftable onthe spindles thereof,.a cam for shifting said bar outwardly along thespindles, and means earried by each support for guiding its stripper barduringv shifting thereof and holding the same yieldingly adjacent to theinner ends of the spindles when free of said cam.

In testimony whereof I aflix my signature.
